Patented Oct. 18, 1938 UNITED STATES PATENT OFFICE 7 Claims.

My invention relates to a new and useful improvement in a hinge andparticularly a hinge of the concealed type.

It is an object of the present invention to provide'a hinge of thisVtype which will be simple in structure, economical of manufacture,durable in use, easily and quickly installed, and one which will notaffect the appearance or mar the beauty of the body on which mounted.

Another object of the invention is the provision of a concealed hinge onwhich a swinging body may be mounted and which will carry the maximumload and afford the desired strength in a hinge of this class.

Another object of the present invention is the provision of a hinge ofthis type, so constructed and arranged that it Will serve, in itself, toform a check on the swinging movement of the body to open position,

Another object of the invention is the provision of a hinge soconstructed that it may be reversed 'for use either as :a right hand -ora left hand hinge and which will accommodate itself to a curved body,such as a stream-lined -vehicle body.

Other objects will appear hereinafter.

The invention will be best understood from a reference to theaccompanying drawing `which forms a part of this specification rand inwhich,

Fig. 1 is a central sectional view of the invention showing it applied,

Fig. 2 is an end elevational view of `the invention with parts brokenaway and parts shown in section, said View being taken substantially :online 2 2 of Fig. 1,

Fig. 3 is a fragmentary view taken on line 3-3 of Fig. 2,

Fig. 4 is a View taken on line 4-'4 of Fig. l,

Fig. 5 is a sectional View taken on 'line 5 5 of Fig. 1,

Fig. 6 is a fragmentary end elevational view of the invention.

The invention is intended for use in mounting a swingable body II on astationary support I2. Particularly on thestream-lined automobilebodies, is it desirable to remove all outward projections. The presentinvention -provides a hinge which may be used in mounting Aa vehicledoor on the vehicle body and the hinge 'itself may be concealed. Thehinge ccomprises'a pair 'of main sections or butts, one of which isU-shaped and embodies the legs I3 and I4 connected bythe Each of theselegs is provided -at its end with the Vangularly turned lugs 'I6 yhavingthe rounded corners -Il. This U-shapedbody is 4the links and through theknuckle 23.

(Cl. 1li- 148) stationary part of the hinge and is housed in a I cavityor recess I5 formed in the .body I2, the angularly turned portions orlugs I6 being secured to the body Yby means of bolts I'I.

The other main portion or butt of the hinge comprises an L-shapedportion, the base 26 of Which is slightly inclined outwardly from theleg I9 and formed shorter than the leg I9. An angularly turned portion2I is formed integral with the base and formed into a .knuckle'22 Latthe juncture of `the portion v2| with the base 20 and also formed into aknuckle 23 at its end. The leg I 9 is secured by the bolts 24 or in anyother suitable manner to the swingable body `or door II.

A pintle extends 4through the legs I3 .and I4 as shown 'in Fig. lE. Thispintle passes through a spacing sleeve 26 andalso through one end of theshort connecting links 2l and 28. The sleeve 26 Ais of such length andthe links 2l and 23 are of such thickness that when these parts are assembled las vshown in Fig. 5 they are vsnugly engaged between the legsI3 and I d.

A pintle -29 yextends through the legs I3 and Ifl and through one end ofthe longer links 3i! and 3-I. of a spring 32. These coils are formedfrom a single piece of wire, the center portion of which is doubled uponitself to provide a tongue 33 and ythe ends 34 and 35 -of which areangularly turned so as to, when the hinge is swung open a predetermineddistance, engage with the faces -oi the links 38 and .3l which `aredirected away from the bight I5. The base '2t is formed of la widthcorresponding-with the length of the sleeve '26 and the links 2l and 28are formed of thel same thickness as are the links 3@ and 3l. The links2l and 28 overlie the knuckle 22 and a pintle 36 is passed through theknuckle 22 and the ends of the links 2'I and 28 so that the portion ofthe hinge which is connected tothe door II Vis pivotally mounted on thepintle 36. The

knuckle 23 llies between the ends of the links 3| and and a pintle 3l ispassed through `these This pintle 31, it will be noted, does not extendthrough the legs I3 and I4 but is of a length to snugly lfit between thesame.

As shown in Fig. 5, the angularly turned ends 34 and 35 .are not inengagement with the links,` 30 and 3i when the door is in closedposition. However, 4as the door swings outwardly as Vshown in the dottedline illustration in Fig. 1, the links 30 and 3I swingfonfthe pintle -29and engage the This pintle also extends through the coils angularlyturned ends 34 and 3,5 of thespring. 5 5

Further outward swinging toward the open position of the door will eiecta further swinging of the links 30 and 3| which would have a tendency towind the coils 32 of the spring. Consequently, this spring functions tocheck the outwardly or opening swinging movement of the door after thedoor has swung toward open position a predetermined distance. The springtherefore serves as a check for resisting open swinging of the doorafter the door has swung' open a predetermined distance and thereforethe check straps which are commonly used on vehicle doors may beeliminated. When the door swings to its fully open position the stopshoulder will engage the knuckle 2G. This engagement however, will be aneasy engagement because of the resistance offered by the spring.

When the door is swung to shut position, the space between the legs I3and I4 will, of course, not be visible, but when the door is swung toopen position, this space would be visible and would seriously affectthe appearance of the body on which mounted. In this invention, I haveprovided means for closing the space between the legs I4 and I3 when thedoor is swung to open position. This is accomplished by means of a plate40 which has, at one end, the lateral extensions or wings 4I,whichoverlie and are adapted to engage one face of the legs I3 and I4.The opposite end of the plate 40 is Vprovided with the inwardly turnedtongues 42 and 43, which are crimped around the leg I9 of the hingesection, so that this plate is slidable on the leg I9. As the door isswung to open position, the wings 4I riding on the legs I3 and I4 willslide the plate rearwardly on the leg I9, so that when the door is swungto fully open position, the plate 40 will serve as a closure for thespace between the legs I3 and I4. As the door is swung to closedposition, the end of the plate 40 will engage the base I5 of the cavityor recess in the body I2 and the plate will be slid into the positionshown in full lines in Fig. 1.

While I have illustrated and described the preferred form ofconstruction, I do not Wish to limit myself to the precise details oistructure shown but desire to avail myself of such variations andmodifications as come within the scope of the appended claims.
